I have two beds on any side of my front door. I had to tear out these HUGE prickly bushes so my kids wouldn't take all scratched up. I now hold a blank slate and we have had lots of problems near spiders, fleas, and ants so I was wondering if there is anything special, herb or flowers, I could plant to keep them away from my front porch. Especially the ants and fleas as I have animals. The spiders go away when I got those bushes out so now I really am down to keeping fleas, ants and wasps away from the front door. Any concept would be really helpful.

I HATE vines and bushes so primarily herbs and flowers you can ponder of. I live in Upstate South Carolina and it is zone 7 so I would like something drought resistant once established and can bar mostly shade and some sun, they are both shady in the morning and one has full sun contained by afternoon for about 4 hours, the other just have some sun filtered through the huge tree all daylight so i guess it is considered primarily shady. Thanks!
Answers:    The local green pest control companies use a Eucalyptus mulch that helps keep bugs away. Then you can choose doesn`t matter what type of plants you like, just be sure to settle up attention to how large the plants will grow and plant accordingly. As far as flowers Marigolds are also used to keep pests away, but they are an anual plant. These are commonly used in gardens. Wax Myrtles, are not the most dense type of shrub, but can be a great filler shrub and get exceptionally tall were used by Native Americans as a mosquito repellent, they would run some leaves and rub them on exposed skin it gives off a peppery smell.
